shared/options: add OPTION_COMMON_{SYSTEM,USER}

We have different help strings for --user/--system in different places, so this
only covers a subset of --system/--user instances. But this particular help
seems to be the most widely used.

(In a few cases, the help string is fixed: it should be "system mode", not
"per-system mode".)
